Dear All,

Sorry about the above title!

I have this sql statement 
$DB->Sql("INSERT INTO Hosts(Host_Name,SAN,location,Country) 
      VALUES ('$host',
              '$clean_data{$host}'SAN'}',
              '$clean_data{$host}{'location'}',
              '$clean_data{$host}{'country'}')");

Then I follow the above with this sql statement to obtain the primary key values of the Hosts record. 
die "Sql Failed" . $DB->Error( ) . "\n" if ($DB->Sql
     ("SELECT Host_ID FROM Hosts WHERE Host_Name='$host'"));
        my $rec_indx;
        while ($DB->FetchRow())
        {
            my %data = $DB->DataHash();
            $rec_indx =  $data{"Host_ID"};
            print qq(index key is $rec_indx\n);
        }

And then with the following code and sql statment, I insert the primary key value into Apps record to create a relationship between the two (I have already created two blank corresponding tables in ms-access with one-to-many relationship between hosts and apps). 
        for my $info (@{$clean_data{$host}{'applications'}}) 
        {
            unless ($seen{@{$info}}++)
            {            
                           $DB->Sql("INSERT INTO Apps  
                             (App_Name,Description,Host_ID) 
                              VALUES ('$$info[0]',
                                      '$$info[11]',
                                      '$rec_indx')");
            }
        }

My question is;
1- Is there away that I could do away with the second sql statement where I can insert the primary key from Hosts record, into the Apps record without having to revisit the host record again? Similar to this suggestion (node_id=463992).
2- How can I in the first sql statement check to see it the hosts record (i.e the hosts name) doesn’t exists before inserting it? So if it exists then I will run a UPDATE statement instead of instead of creating it?

I am using Win32::ODBC and ms-access.

Thanks very much
